Like other ergonomic keyboards, the Wave includes an elevated palm rest, though not as extreme as the platforms of old. It's also covered in a lightly padded vinyl upholstery that feels soft yet firm under the wrist, as well as a Goldilocks amount of tackiness (i.e., not too slippery, not sticky, just right). The keys are also positioned in a gentle U-shaped arc that nearly escapes the eye, but is apparent once you set your wrists down and start typing.

Contoured, wave-shaped key design conforms naturally to your fingers.

As someone who writes for a living, my computer keyboard is one of the most important tools I have and one that I'm connected to for hours every day. I've gone through many models over the years to get just the right one, and I currently use the Matias Tactile Pro on my Mac as it provides some of the best keystroke feedback I've found (which is the polar opposite to the frustratingly squishy keyboards that came with my HP and Apple PCs).

While the rolling contour of the keyboard layout was barely perceptible, my fingertips took to the Wave easily. It felt like each key was indeed designed specifically to fit the finger that was mapped to tap it. And the keys combine a springy action with a final tap that's not too loud, but both tactile and audible enough for instant feedback. As my week of testing progressed and my fingers grew more accustomed to the Wave, I actually felt as if my typing was both more accurate than on the Tactile Pro as well as a touch faster.

From an ergonomic standpoint, the Wave's gradual curve isn't immediately noticeable, but after a few days I found my elbows weren't hunched next to my body as they were with the straight keyboard, freeing both wrists and shoulders from strain. That said, if you require more substantial ergonomics for your typing (such as the curve and height of the Microsoft Natural), you might be disappointed by the relative flatness of the Wave.

The keyboard is supplemented by a plethora of system-specific feature buttons--including Flip 3D, Gadgets and Media Center in Windows Vista (aka, Expose, Dashboard, and Front Row on the Mac)--as well as quick access to your selected audio program and full playback controls (including volume). All functions can be customized using the included Logitech Setpoint utility (or Control Center within the Mac's System Preferences).

When I began reviewing the Cordless Wave, I wasn't looking for a new keyboard. But thanks to its excellent typing action, unique comfort features--from the contoured design of the keys to the padded wrist rest--and the plethora of customizable functions right at the tip of the finger, it's time to part ways with my old keyboard. --Agen G.N.
